Informed by the Cognitive Mediation Model of media learning, this study explores how self-efficacy and information-processing strategies jointly impact the learning of health knowledge. Using survey data (N=1409), the study examines the roles that self-efficacy, motivation of media use, news attention, and elaboration play in acquiring knowledge about swine flu during the 2009 global pandemic crisis. Results support the hypothesized relationships among self-efficacy, motivation, attention to and elaboration of swine flu news, and knowledge about the flu. Implications of the findings to advance the research in mediated cognitive learning are discussed. 相似文献

ABSTRACTA deliberative democracy is reliant on an informed electorate discussing issues and presenting persuasive arguments. Individuals acquire information from exposure to political messages. Partisan cues, however, undermine learning outcomes. The current study experimentally examines the social cognitive processes that underlie this learning process. Integrating the social identity theory, elaboration likelihood model, and the theory of motivated reasoning to construct the theoretical concept of identity-motivated elaboration, the results indicate that partisan social identities motivate biased processing of new information, which subsequently influences the valence of elaboration. Positively and negatively valenced elaboration are situated as mediating variables in the structural model, which predicts learning from a persuasive political message. The current study extends the partisan social identity hypothesis to the elaborative and learning outcomes of political messages. 相似文献

This study investigates the framing effects of gay-themed entertainment media in China. Specifically, the study explores the mechanisms underlying attribution framing and value framing, through two separate experiments. The results of the first experiment indicate that exposure to attribution frames had considerable influence on the participants' perceptions of the controllability of homosexuality and their emotional responses. In addition, fictional entertainment media's framing of the origin of homosexuality indirectly influenced the participants' opinion through anger. Those participants exposed to a program homosexuality as a type of ‘controllable’ sexuality were likely to express anger and thus were not likely to support gay rights. The results of the second experiment indicate that the core values reflected in a gay-themed program affected the participants' opinions by changing their perception of the importance of value-related beliefs. Those participants exposed to a frame reflecting family values were likely to consider beliefs about family values to be important, which facilitated their support for gay people's personal dignity and equal rights to jobs, housing, and freedom of expression, among others. 相似文献

ABSTRACT Anita Hill’s testimony against Clarence Thomas in 1991 called attention to widespread sexual abuse in the US. Testimony from Christine Blasey Ford against Thomas Kavanaugh 27 years later underscored the lack of progress in its eradication. Using the cascading network activation model, this study identifies the episodic and thematic framing of both cases in relation to top-down influencers. A content analysis (N = 901) of US newspapers and TV networks showed episodic framing dominated coverage in both cases. Both Bush and Trump successfully emphasized their nominee as deserving of SCOTUS. Trump also significantly contributed to the negative framing of Blasey Ford. Thematically, Republican-led framing focused on American values and maintaining the rule of law, whereas Democratic-led framing concentrated on raising awareness to the systemic problem of sexual abuse and threat the nominee posed to progressive rights. News coverage included challenging both presidents, but only for a total of 15.9% for Trump and 10.7% for Bush. On the other hand, Hill was challenged in 40.5% and Blasey Ford in 73% of news coverage. In sum, even with strong opposition, the cascade model’s success indicates that White House messaging continues to usurp social justice issues. 相似文献

ABSTRACT The study explored how the combinations of living-with-HIV portrayals and HIV onset controllability portrayals influence HIV stigma because the two frame coexist in our communication environment. Results from an experiment with 443 college students in the United States indicated different combinations of the two frames might be helpful, ineffective, or harmful in reducing HIV stigma. The positive portrayal-low onset controllability combination might reduce HIV stigma, the negative portrayal-low onset controllability combination might be ineffective in reducing HIV stigma, and the positive portrayal-high onset controllability combination and the negative portrayal-high onset controllability combination might even increase HIV stigma. These results contextualize the effectiveness of positive portrayals of living with HIV when audiences may be exposed to multiple frames of messages about HIV stigma; they highlight the potential interactions between the two frames that may reduce the effectiveness of anti-stigma messages or may be used against the efforts to reduce HIV stigma. 相似文献

Comparative framing analysis on coverage of the North Korean nuclear test in the US Associated Press, Chinese Xinhua, and South Korean Yonhap news agencies identified four major media packages. First, a common ‘threat’ frame dominated coverage by all news agencies, represented by reconfiguration of geopolitics and an emphasis on global cooperation in both perception and resolution of the nuclear test. Second, with each nation positioning itself differently in the world power system, the issue was notably domesticated in the news, with Associated Press connecting the nuclear test to the broader ‘War on Terror’ framework found frequently in US media, Xinhua promoting a negotiation principle in handling the issue, and Yonhap framing the test with a ‘Cold War’ perspective. In all three cases, national political interests exerted important impacts on the construction of frames. The compatibility of the seemingly opposite packages (globalizing vs. domesticating) signifies both intensification of worldwide social relations and reassertion of national stands. This finding lends support to the transformationalist view of globalization, which suggests that the nation state still matters in a globalized world, but is being recontextualized in a more complex world of politics and culture. 相似文献

In 2015, Houston, Texas voters defeated a bill that would have expanded civil rights to previously unprotected groups, including transgender people. Using a critical framing analysis, this paper investigates how the city’s daily newspaper, the Houston Chronicle, covered the debate over the bill. As such, this study found that the newspaper used almost exclusively elite sources, provided almost no in-depth context, and employed four frames—Equality, Bathroom Boogeyman, Bureaucratic Process, and Religious Freedom—in its Houston Equal Rights Ordinance (HERO) coverage. Together, these elements aligned to form a daunting challenge to an effort to protect one of society’s most vulnerable groups: the transgender community. 相似文献

This research investigated the influence of message framing (gain or loss) and temporal distance (present or future) on the intention of Human papillomavirus (HPV) vaccination. A total of 156 Chinese undergraduates participated in a controlled experiment in Macau, a Special Administrative Region of China. Results showed that message framing and temporal distance interacted to impact the intention of HPV vaccination. Particularly, among participants who had no prior knowledge of HPV vaccine, the gain-present and loss-future framed messages resulted in more positive attitudes toward the message, higher degree of perceived severity of HPV infection, and more likelihood to get HPV vaccination than the gain-future and loss-present framed messages. Implications of the findings were discussed. 相似文献

This study examines the stories acquaintance rape victims tell through semi-structured interviews. Acquaintance rape, viewed here as a particularly paradoxical crime, creates a need for women to resolve the inconsistency of their experience. By conducting interviews with victims and analyzing their verbal communication, this project explores how victims frame their rape experience. Framing strategies used by victims of sexual harassment served as a guide for the initial identification of framing strategies for victims of acquaintance rape. Women in this study utilized strategies of paradox management to assess blame, define, and reframe their experiences. Recognition of these management strategies can assist social support networks and law enforcement professionals in identifying the communicative strategies of female victims of varying types of violence. 相似文献

This paper analyzes how major U.S. print and broadcast news media framed depression causal and problem-solving responsibilities at individual and societal levels over the past three decades. Results from the content analysis showed that the media placed more causal and problem-solving responsibilities on individuals than the society. However, references to societal solutions increased moderately over time. Organizational differences emerged in news attribution of responsibilities, as print media presented more individual-level causes while broadcast media focused more on solutions at both individual and societal levels. Additionally, local newspapers put more problem-solving responsibilities on individuals than national newspapers, while a cable news channel allocated more time to the discussion of overall depression responsibilities than network TV. Findings are discussed in the context of cultural orientations, organizational constraints, changing practice and trends in health news reporting, and the broader political/social environment in which the news media operate. Practical implications for health journalism, mental health communication and advocacy, and public health policy-making are discussed. 相似文献

In many probabilistic modeling approaches to Information Retrieval we are interested in estimating how well a document model “fits” the user’s information need (query model). On the other hand in statistics, goodness of fit tests are well established techniques for assessing the assumptions about the underlying distribution of a data set. Supposing that the query terms are randomly distributed in the various documents of the collection, we actually want to know whether the occurrences of the query terms are more frequently distributed by chance in a particular document. This can be quantified by the so-called goodness of fit tests. In this paper, we present a new document ranking technique based on Chi-square goodness of fit tests. Given the null hypothesis that there is no association between the query terms q and the document d irrespective of any chance occurrences, we perform a Chi-square goodness of fit test for assessing this hypothesis and calculate the corresponding Chi-square values. Our retrieval formula is based on ranking the documents in the collection according to these calculated Chi-square values. The method was evaluated over the entire test collection of TREC data, on disks 4 and 5, using the topics of TREC-7 and TREC-8 (50 topics each) conferences. It performs well, outperforming steadily the classical OKAPI term frequency weighting formula but below that of KL-Divergence from language modeling approach. Despite this, we believe that the technique is an important non-parametric way of thinking of retrieval, offering the possibility to try simple alternative retrieval formulas within goodness-of-fit statistical tests’ framework, modeling the data in various ways estimating or assigning any arbitrary theoretical distribution in terms. 相似文献
